In the Navy, my barracks roommate was kind of dumb. Not only did I convince him that dragons used to be real creatures that were hunted and slain to extinction during the middle ages, but one week later, I convinced him that he was the one who told me about it.
I had a whole elaborate backstory about how they had specialized pouches in their mouths that would contain food from what they’ve eaten and could hold and store methane from that food rotting in those pouches. I said that they could expel this methane and ignite with sparks from bits of flint in their teeth. This was his they breathed fire.
Why did they have flint in their teeth? I’m just glad he didn’t ask the question 🤣
